I found info on #define and #include in the reference section but could not find info on #if, #else, #ifdef, #endif, etc also no sign of PROGMEM reference either... Is there another reference area that I am missing? I am trying to understand a sketch but have never run into those commands before …

Looking for reference info on #if, #else, #ifdef, #endif, etc
